Method Detail

matchesPrototype

protected static boolean matchesPrototype(java.lang.Class[] inPrototypeClasses,
                                          java.lang.Class[] inParameterClasses)

Utility method to determine if a given parameter class array matches the supplied prototype class array

Parameters:

inPrototypeClasses - the prototype that is used in the comparison

inParameterClasses - these are the parameter classes that must be validated against the prototype

Returns:

whether the parameter classes match the prototype

matchesItem

protected static boolean matchesItem(java.lang.Class inPrototypeClass,
                                     java.lang.Class inParameterClass)

Utility method to determine if a given class matches another class, taking into account primitive<->class mapping and inheritance.

Parameters:

inPrototypeClass - TODO: Describe the Parameter

inParameterClass - TODO: Describe the Parameter

Returns:

TODO: Describe the Return Value

doAction

public java.lang.Object doAction(java.lang.Object inModel,
                                 ModelAction inAction,
                                 java.lang.Object[] inParameters)
                          throws java.lang.Exception

Execute the ModelAction with the given parameters

Specified by:

doAction in class ActionManager

Parameters:

inModel - The model used for executing the ModelAction

inAction - The action (method) to execute

inParameters - The parameters of the method

Returns:

The result of the ModelAction method

Throws:

java.lang.Exception - if the execution of the ModelAction failed for any reason

canDoAction

public boolean canDoAction(java.lang.Object inModel,
                           ModelAction inAction)

Returns true if the ModelAction can be executed on the model object.
If the model implements DynamicInvokable, then check that the ModelAction can be invoked by calling the isActionInvokable() method on the model.

Specified by:

canDoAction in class ActionManager

Parameters:

inModel - The model used for executing the ModelAction

inAction - The action (method) to execute

Returns:

true if the ModelAction can be executed on the model

getMethod

protected java.lang.reflect.Method getMethod(java.lang.Object inModel,
                                             ModelAction inAction)

Find a Method matching the prototype in the passed ModelAction for the passed model object, using the BeanInfo to introspect the model as a JavaBean.

Parameters:

inAction - find a Method that matches the prototype described in this ModelAction.

inModel - The model used for executing the ModelAction

Returns:

a Method matching the ModelAction for the passed model or null if no match.
